yeap -- but Debian makes it so easy to get any kind of such an
environment, that for me use of a few more megs of disk space is not
really a cost to even worth mentioning ;)

and initially expose those as an apt repository, adjust apt configuration on
every node... Then have 2 stage upgrade procedure (in first wave it
would rebuild locally build beasts, and place them into APT repo, then
apt-get update and {dist-,}upgrade to pick them up).
I am not saying that it all couldn't be done, I am just saying
that for a user it is not available out of the box without manual
configuration etc.
